Korean Leveraged Single-Stock ETF Investors Face Heavy Losses, Minister Apologizes

South Korea's Finance Minister Koo Yun-cheol has issued an apology following substantial losses incurred by retail investors in single-stock leveraged exchange-traded funds (ETFs). A sharp decline in the semiconductor sector, particularly among major chip stocks, led to significant financial setbacks for investors who had heavily allocated capital to these high-risk products, which were introduced in May. Lee Eog-weon, Chairman of the Financial Services Commission (FSC), also expressed regret and indicated that additional regulatory measures are being considered, including potentially limiting access to these products to professional investors only.

Single-stock leveraged ETFs were launched in the South Korean market on May 27, 2026, quickly gaining popularity among retail investors betting on robust demand for artificial intelligence (AI) chips. According to data from KB Financial Group, Korean retail investors made net purchases of approximately 14 trillion won (around $9.7 billion) into these products, significantly outweighing the roughly 2 trillion won in net purchases by foreign investors. These ETFs were specifically designed to track major chipmakers like Samsung Electronics (SSNLF) and SK Hynix (SKHY), aiming to deliver twice their daily price movements.

However, an unexpected downturn in chip stocks triggered substantial losses across these leveraged products. For instance, the KODEX SK Hynix Single Stock Leverage ETF, which tracks SK Hynix shares, has plummeted over 80% since its peak on June 23. This severe market movement contributed to the benchmark KOSPI index falling as much as 12.6% on July 29. The sharp decline in the index was largely driven by losses in Samsung Electronics and SK Hynix, which together account for nearly half of the index's market capitalization.

Financial regulators have faced considerable criticism for exacerbating market volatility and exposing retail investors to undue risk. The initial rationale behind introducing these products was to prevent domestic capital from flowing overseas to chase similar leveraged products already available in U.S. markets. Nevertheless, the current situation has led to strong criticism, suggesting that regulators may have underestimated the inherent risks associated with these investment vehicles.

In response to the market turmoil, the Financial Services Commission has moved to tighten regulations on single-stock leveraged ETFs. Effective July 31, the minimum cash deposit requirement for investing in these products has been raised from 10 million won to 30 million won, and non-cash collateral will no longer be accepted. Furthermore, new listings of single-stock leveraged ETFs have been temporarily halted, and investors are now required to complete mandatory risk education sessions. These measures aim to curb speculative trading and enhance investor protection, although some experts warn that such restrictions might simply shift demand to overseas markets.
